闽江3种类型河岸带自生草本植物生物量、多样性、功能性状及其与土壤因子的关系
Ground biomass,diversity,functional traits of spontaneous herbaceous plants and their relationships with soil factors in 3 types of riparian zones along the Minjiang River
摘要
Abstract
[Objective]This study explored the aboveground biomass(AGB),species diversity,functional trait characteristics of the spontaneous herbaceous plant communities and their relationships with soil factors in 3 types of the riparian zones of Fuzhou section of the Minjiang River,providing a theoretical reference for the ecological restoration of riverbank zones.[Method]Focusing on the dominant species of spontaneous herbaceous plant communities in the Fuzhou section of the Minjiang River,the community charac-teristics,functional traits and soil factors of spontaneous herbaceous plant in building riparian zone,farming riparian zone(FRZ)and natural riparian zone(NRZ)were analyzed.And the relationships among factors and their effects on aboveground biomass were also discussed.[Result]Significant differences in soil physicochemical properties were observed among different types of riparian zones.With the increase of disturbance,lower soil moisture content(SMC),gradually higher soil bulk density and gradually smaller plants AGB were observed;NRZ had relatively lower soil pH value,while FRZ had dramatically higher soil electrical conductivity and soil salt content(SSC)(P＜0.05);significant differences were found in plant height,leaf thickness,leaf dry matter content and leaf water content among different riparian zone types(P＜0.05).Soil pH value,SMC and SSC were the primary factors affecting the AGB,species diversity and functional traits of the dominant spontaneous herbaceous plant communities.[Conclusion]Significant differences were observed in soil factors,community characteristics and functional traits of spontaneous herbaceous plant among dif-ferent types of riparian zones(P＜0.05);species diversity and plant functional traits jointly drove the AGB response of spontaneous herbaceous plant to soil factors.关键词
